I have this model, the tl-wr841hp v5, which I recently acquired more detailed information: https://deviwiki.com/wiki/TP-LINK_TL-WR841HP_v5.x
but the problem is that there is no support for OpenWrt, well, it is not in the openwrt table, but when browsing the openwrt website I found several models with the same processor and small features
First, it is the CPU, mine is 575 mhz but in other routers it is 580 mhz
second is storage on some models. I have found that the speed is the same as that of my router, but the storage is 32MB and 64MB RAM.
well finally i would like to know how to modify those parameters or someone could compile one since i am new to this openwrt
